Title: Method and device for recording optical recording medium
Inventor: SASA NOBORU
IPC: G11B7/125
Filed: 1999-11-29
Abstract: PROBLEM TO BE SOLVED: To enable the recording by the easy control method while being applicable for the CAV and ZCAV, or the CLV recording with an optional velocity. SOLUTION: In this method, so-called rectangular wave recording is used, with which the recording operation is executed by only one light emitting pulse for forming a recording mark. The recording power of the rectangular waveform, or this recording power and the light emitting pulse length are controlled in accordance with the recording position or the recording linear velocity of the optical recording medium. The control of the light emitting pulse length is performed by the control of the TSFP and TLE. The continuous setting/changing of the recording pulse length in accordance with the broaden recording linear velocity is attained by the subject method and device.  Since the pulse intermittent part like the case of the multi-pulse recording method is not in existence even when the recording linear velocity is changed, the control of the recording pulse length for correcting the state of the thermal diffusion and thermal interference is simplified. By this method, specially when the recording pulse length is controlled, the satisfied jitter property is obtained with the broaden recording linear velocity in the manner of controlling only the light emitting pulse lengths with respect to the shortest mark and next shorter mark lengths in accordance with the recording linear velocity.
